while package it with pyinstaller then run exe-file, it occur FileNotFoundError with temp-user-path like c:\Users\userName\AppData\Local\Temp\_MEI**\Equattion

Details error occur in Equation_init_.py line 93 and 75 while loading.

Dynamic load from abs path makes it failed.

Equation is very good but Finally I use parse_expr and lambdify in sympy instead.

hi @xflyyxfl could you explain how you solved it? i have a solver for Euler Differential Equation:

def EulerEcDif(self):
        f = Expression(self.dxdyfld.get(), ["y", "x"])
        x = float(self.x0cifld.get())
        y = float(self.y0cifld.get())
        xn = float(self.xnfld.get())
        n = int(self.nfld.get())

        solx = []
        soly = []
        solx.append(x)
        soly.append(y)
        h = float(xn - x) / n
        while x < xn:
            print('\nAt x=%.4f, y=%.4f' % (x, y))
            y = y + f(x, y) * h
            x = x + h
            solx.append(x)
            soly.append(y)
        plt.plot(solx, soly)
        plt.xlabel('x')
        plt.ylabel('y')
        plt.show()

and i'm trying to convert it to parse_expr but i cannot make it work. dxdyfld is where i write the expression
